The discovery suggests that early human ancestors began eating meat much earlier in history than previously believed.

New study sheds light on cancer-protective properties of milk Posted: 03 Oct 2012 01:37 PM PDT Milk consumption has been linked to improved health, with decreased risks of diabetes, metabolic syndrome, and colon cancer. Scientists found that lactoferricin4-14, a milk protein with known health effects, significantly reduces the growth rate of colon cancer cells over time by prolonging the period of the cell cycle before chromosomes are replicated. In a new study, investigators report that treatment with Lfcin4-14 reduced DNA damage in colon cancer cells exposed to ultraviolet light.

Mom's high blood pressure in pregnancy could affect child's IQ into old age Posted: 03 Oct 2012 01:36 PM PDT New research suggests that a mother's high blood pressure during pregnancy may have an effect on her child's thinking skills all the way into old age.

Ensuring high-quality dietary supplements with 'quality-by-design' Posted: 03 Oct 2012 12:09 PM PDT If applied to the $5-billion-per-year dietary supplement industry, "quality by design" -- a mindset that helped revolutionize the manufacture of cars and hundreds of other products -- could ease concerns about the safety and integrity of the herbal products used by 80 percent of the world's population.

New evidence on easing inflammation of brain cells for Alzheimer's disease Posted: 03 Oct 2012 12:09 PM PDT New research proves the validity of one of the most promising approaches for combating Alzheimer's disease with medicines that treat not just some of the symptoms, but actually stop or prevent the disease itself, scientists are reporting. The study also identifies a potential new oral drug that the scientists say could lead the way.

Discovery leads to new hope against ovarian cancer Posted: 03 Oct 2012 12:09 PM PDT Scientists have discovered a new type of drug for the treatment of ovarian cancer that works in a way that should not only decrease the number of doses that patients need to take, but also may make it effective for patients whose cancer has become drug resistant.

Runners' foot injuries could be due to ill-fitting shoes Posted: 03 Oct 2012 12:07 PM PDT Researchers are conducting a first-of-its kind study of marathon runners to determine if there is link between foot injuries and ill-fitting shoes.

Onset of flu season raises concerns about human-to-pet transmission Posted: 03 Oct 2012 11:10 AM PDT As flu season approaches, people who get sick may not realize they can pass the flu not only to other humans, but possibly to other animals, including pets such as cats, dogs and ferrets. This concept, called "reverse zoonosis," is still poorly understood but has raised concern among some scientists and veterinarians.

Dozens of new de novo genetic mutations in schizophrenia identified Posted: 03 Oct 2012 10:24 AM PDT Researchers have identified dozens of new spontaneous genetic mutations that play a significant role in the development of schizophrenia, adding to the growing list of genetic variants that can contribute to the disease. The study is the largest and most comprehensive of its kind.

Inability to conceive is extremely stressful for women who want to have a family.

Got dry eyes? Measuring eyelid sensitivity may reflect the causes Posted: 03 Oct 2012 08:11 AM PDT A simple test of eyelid sensitivity may help vision professionals in evaluating one of the most common eye-related symptoms: dry eyes. A new study links increased eyelid sensitivity to decreased function of the eyelid margins.

Balancing fertility and child survival in the developing world Posted: 03 Oct 2012 05:29 AM PDT Children in smaller families are only slightly more likely to survive childhood in high mortality environments, according to a new study of mothers and children in sub-Saharan Africa seeking to understand why women, even in the highest fertility populations in world, rarely give birth to more than eight children.

Surgeons recreate eggs in vitro to treat infertility Posted: 03 Oct 2012 05:29 AM PDT Regenerative-medicine researchers have moved a promising step closer to helping infertile, premenopausal women produce enough eggs to become pregnant. Surgeons have now reported that they were able to stimulate ovarian cell production using an in vitro rat model, and observed as the cells matured into very early-stage eggs that could possibly be fertilized.

Surgeons pilot expandable prosthetic valves for congenital heart disease Posted: 03 Oct 2012 05:29 AM PDT Surgeons have successfully implanted a modified version of an expandable prosthetic heart valve in several children with mitral valve disease. Unlike traditional prosthetic valves that have a fixed diameter, the expandable valve can be enlarged as a child grows, thus potentially avoiding the repeat valve replacement surgeries that are commonly required in a growing child. The new paradigm of expandable mitral valve replacement has potential to revolutionize care for infants and children with complex mitral valve disease.

Chloroquine makes comeback to combat malaria Posted: 03 Oct 2012 05:29 AM PDT Malaria-drug monitoring over the past 30 years has shown that malaria parasites develop resistance to medicine, and the first signs of resistance to the newest drugs have just been observed. At the same time, resistance monitoring shows that the previously efficacious drug chloroquine is once again beginning to work against malaria. In time that will ensure cheaper treatment for the world's poor.

Study findings suggest reproductive hormones contribute to regulation of immune responses in autoimmune diseases such as MS.

The genetics of HIV-1 resistance Posted: 03 Oct 2012 05:27 AM PDT Drug resistance is a major problem when treating infections. This problem is multiplied when the infection, like HIV-1, is chronic. New research has examined the genetic footprint that drug resistance causes in HIV and found compensatory polymorphisms that help the resistant virus to survive.

Increase in allergies is not from being too clean, just losing touch with 'old friends' Posted: 03 Oct 2012 05:27 AM PDT A new scientific report dismantles the myth that the epidemic rise in allergies in recent years has happened because we're living in sterile homes and overdoing hygiene. But far from saying microbial exposure is not important, the report concludes that losing touch with microbial 'old friends' may be a fundamental factor underlying rises in an even wider array of serious diseases.

Nanoparticles against aging Posted: 03 Oct 2012 05:27 AM PDT Scientists have developed an intelligent nanodevice that lays the foundations for the future development of new therapies against aging.
